Introduction to the Electronic Piano
The electronic piano is a keyboard instrument that is actually an electronic synthesizer. The electronic piano is actually not a correct name at all, because it resembles a piano, so some people call it the electronic piano. In fact, the formal name should be electronic synthesizer. It uses large-scale integrated circuits, most of the configuration of the sound memory memory (wavetable). It is used to store the real sound waveforms of various types of instruments and output them when playing. Commonly used electronic piano has two categories of arranger keyboard (with automatic accompaniment) and synthesizer (without automatic accompaniment), broadly speaking, electronic piano including electronic piano (digital piano, differentiated from the electro-acoustic piano), more use of the five-line score, mostly for the treble and bass double line notation. Sometimes also use the alto clef and simple sheet music, guitar sheet music. Generally used for rock music.
Electronic musical instruments
First of all, it is imitated the "king of musical instruments" pipe organ (PipeOrgan). The pipe organ was invented in BC and flourished in the 17th century. It is a musical instrument that relies on water power or human power to blow the wind and sound the pipes as tall as the building. Pipe organs are large keyboard instruments with a very complex structure. Pipe organs are composed of a hand keyboard and a foot keyboard, some of which have as many as 4-5 layers. A pipe organ can rival an orchestra in performance. Pipe organs are complex, bulky, expensive, and not easy to move due to the limitations of performance venues and environments. In order to make it lightweight, in 1907, the American T_Cassier invented an electric organ with electromagnetic coils to generate scale signals. 1920, the Soviet Union, Leon Trier invented the "aerial electric organ". 1939, the United States began to sell the "Allen Organ", which is an electronic organ that can be compared with an orchestra. In 1939, the U.S. market began to sell "Allen Organ", this electronic organ is lighter and more economical than the pipe organ, commonly used in teaching, concert halls, and so on, and thus has a certain market. To 1950, the United States annual production of electronic organs up to 100,000 units, close to the piano production. 1964, the American Mug invented the synthesizer.
